Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529508, here are decompositions:

29 + 31529479 = 31529508
37 + 31529471 = 31529508
61 + 31529447 = 31529508
149 + 31529359 = 31529508
229 + 31529279 = 31529508
239 + 31529269 = 31529508
251 + 31529257 = 31529508
359 + 31529149 = 31529508

Showing the first eight; more decompositions exist.
